I believe the answer is "C. When your cells need more oxygen."
Please mark brainliest, if right. Thanks :)
Answer:
The correct answer will be option A.
Explanation:
The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.
This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.
Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.
Thus, option-A is the correct answer.
The answer is: [B]: "Very low levels of telomerase."

Answer: Medical science is a very interesting feild in science, there is many different ways someone could go with this. For example there is suddies in small organisms like viruses and there is also anatomy. Veterinary scientists need to have a strong interest and skills in science and research. A interesting position to take on being in health science could be medicine because it connects many of the smaller feilds in medical sciences. Medicine is a great area to study because it can only improve and in the world people live in these days it is really important to earth. Medical sciences is a great subject to study for many reasons.
Answer:
A nerve impulse from one neuron affects the activity of a neighboring neuron at a point of interaction called the: SYNAPSE
Explanation:
A NEURON(or nerve cell) has 3 parts:
1. The dendrites(multiple)
2. The axon
3. The cell body
A SYNAPSE is an area where the dendrites of one neuron communicates with the axon of another neuron.
At the synapse, nerve impulses are transmitted from one neuron to the other. This is possible through substances called NEUROTRANSMITTERS. There is no direct contact between the axon of one neuron and dendrites of another neuron.
